Zipp’s Super-9 Track Tubular Disc AUS is available in front and rear wheel. These track-only discs were developed to help Cycling Australia take on the world. As an official partner of Cycling Australia, Zipp provides disc wheels for international velodrome events including the team pursuit. These Super-9 discs will be used by Cycling Australia with a specific design to interface with the squad’s Argon 18 track bikes. The Super-9 Track Tubular Disc AUS, handmade at our factory in Indianapolis, USA, optimizes supreme aerodynamics, power transfer, stiffness, lightweight and durability. The wheel remains flat from its widest point to the hub. The result is unmatched speed on the velodrome.
